(CNN) -- Celine Dion checked into a Florida hospital Sunday night as a precaution "to prevent the early delivery of her babies," the hospital said in a written statement Monday.

The superstar singer and her husband Rene Angelil are expecting twin boys in November.

The couple chose to have their babies delivered at St. Mary's Medical Center in West Palm Beach, Florida, according to the statement.

"She has been admitted to prevent the early delivery of her babies which is the standard of care for any patient with twin pregnancy in this clinical setting," the statement said. "This is done to ensure the patient can be in close contact with their doctors and clinical resources, leading up to their birth.

Her doctors want Dion to remain in the hospital at least until the first week of November, when she would be 37 weeks along in her pregnancy, her representative said.

Dion, 42, revealed in July that she was pregnant with twins after her sixth round of in vitro fertilization.
